State on quality of Chinese gum rosin from 1995 through 2002 was investigated in detail.

從各種不同渠道詳細調查了1995年至2002年中國脂松香的質量狀況思思热视频在线精品视频。

As results, the contents of three original pimaric-type resin acids, namely pimaric, isopimaric and sandaracopimaric acids, generally decreased, the higher the initial content with the higher the temperature and longer time, the faster the content declined.

結果表明，脂松香中原有的3種海松酸型樹脂酸即海松酸亚洲国产欧洲中文字幕、異海松酸男女互搞黄色网站、山達海松酸的含量總體呈下降趨勢，初始含量越高亚洲视频人人干、熱處理溫度越高日韩网络福利直播网站、時間越長，其含量下降幅度越大成人网站日韩在线视频观看网址。

The morphological variation characteristics of resin acid ,as well as titration correction of the unsaponifiable matter during rosin saponification were discussed theoretically.

Thirdly, the acrylic rosin was synthesized by the addition reaction from gum rosin andacrylic acid. The levo-pimaric acid was converted into acrylic pimarie acid throughDiels-Alder addition with acrylic acid. The abietic-type acids in the gum rosin were inisomerization balance under high temperature, and the abietic acid and palstric acid would beconverted into levo-pimaric acid and reacted in the later type.
